14 Although the pagan shrines were not removed, Asa’s heart remained completely faithful to the LORD throughout his life.
15 He brought into the Temple of the LORD the silver and gold and the various items that he and his father had dedicated.
16 There was constant war between King Asa of Judah and King Baasha of Israel.
